Description
This security bulletin contains information about 1 vulnerability.
1) Type Confusion (CVE-ID: N/A)
CWE-ID: CWE-843 - Type confusion
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows an attacker to supply an object of an unintended type to a GraphQL-Ruby argument.
The vulnerability exists due to missing type validation when loads: references an Object type absent from schema return types, including members of returned Interface or Union types. An attacker can submit an ID resolving to a different type and have that object accepted instead of the required type.
